To a/ZZ whom it may concern,.-

Be it known that I, ROBERT STITTs, a citizen of the United States,residing at Dawson,`in

out in full in the specification and claims and are illustrated in theaccpmpanyingdr'awings, 20,in which- Figure 1 is a side elevation of thechair in its normal position. Fig. 2 is a side elevation in shavingposition. Fig. 3 is a top plan of Fig. 1. Fig. 4 is a verticalsection'on the line 4 4 of Fig. 3. Fig. 5 is a similarlsection on theline 5 5 of Fig. 1. Fig. 6 is a section on the line 6 6 of Fig. 5.Fig.`7 isa View ofthe tool-"case, and Fig. Srepresents the seat in anelevated position. i f

The chair proper rests upon the support,

which may be, as shown, in the form of a tripod, or it may becylindrical or conical, as is obvious. Within the space inclosed by thelower portion of the su pportis a cylinder 2,

into which at 3 steam or compressed gas or air is conducted to serve asa motive Huid for raising the chair. A `piston 4, Fig. 4, is littedwithin the cylinder and is mounted upon a stem 5, which extends upwardlythrough a guide 6, occupyingvthe upper central portion of thesupport,'and thence projects through the head 7 of the tripod and a disk8, to the llatter of which it is keyed at 9, the base of the chairproper resting pivotally over the end of the stemupon the'disk. Theinner v a gradual `an olf;r1(')`t ya" sudden descent of the stem 5. Inthe lower portion of the cylinder a valve 12, controlled by thefoot-lever 13, provides for the relief of the fluid-pressure, gas, yor.steam when the chair is lowered;

When it is desired to elevate the chair, steam 5 5 or gas or air underpressure from a suitable storage-tank or from a foot-pump is introducedat 3 and the piston rises, imparting aslow rotary movement to the stemand carrying upwardly the disk and the chair resting thereon. To lowerthe chair, the foot-lever 13 is depressed, the valve 12 opened, and theescape of the 'luid permits a reverse movement of the parts. l Theframework of the chair consists of metallic intersecting rods soarranged as to form a basket-work construction which is of eX- ceptionalstrength, while of light weight and appearance. The rods are preferablyof polished brass of about five-eighths-inch diameter and at the pointsof intersection are joined by brass balls. The framework may also,obviously, be nickel-plated or enameled or may even be more or lessadvantageously made of other material, although, as stated, brass ispreferred. Y The chair proper comprises the seat portion 14, thehead-rest portion 15, and the foot-rest portion 16, the independent andrelativeadjustments of which portions and the means of 8O effecting thesame will be described in turn. The chair rests upon a rigid base-plate17, which contains a central opening for the reception of the upper endof the stem 5, forming a pivotal mounting concentric of the disk 85. 8.The 4plate is provided with an aperture within which a pin 18 is soarranged that in its lowermost position it engages one of the recesses19, formed in a circle in the upper face of the disk l8, and locks thechair to the disk and against relative rotary movement. A rock-shaft 20,suitably journaled `in the frame, carries at one end the operating-lever21 and at the other end an arm 22, which is connected with the pin 18,whereby the latter may be brought into and out of engagement with therecesses 19, the rock-shaft and its parts being held in thedesiredadjustment by means of the pawl 23 engaging the teeth of the rack24.v By the arrangement just de-y IOO scribed the chair can be normallysecured against rotary movement or freely revolved at will, and itcan bereleased, so asrnot to r0.- tate with the disk and the stem as the chairis raised and lowered.

The base-plate 17 has upwardly-projecting lugs or ears 25, within whichis journaled a cam 26, carried by a shaft 27, controlled by a lever 28.This cam 26 is journaled beneath the seat, which rests upon the edge ofthe cam-face 26 and also upon the upwardly-projecting lugs or ears 25. Alever 28, by means of which the cam is operated, is secured to one endof the shaft 27, and by turning said lever the earn-face 26 can beturned upward or downward, thus raising or lowering the seat 29independently of the rest of the chair. The object of the cam and itsposition and operation is to enable the seat to be raised or lowered tosuit the height of the person sitting thereon7 thus accommodatingdierent customers according to their stature, such as a man or a hoy.The seat is guided for vertical movement and against lateraldisplacement by means of the rods 30, which slide in correspondingapertures in the base-plate 17 and frame. These rods 30 fit loosely, andthey may be entirely withdrawn and the seat portion removed from thechair, if desired.

The head-rest portion comprises ahead-rest support in the form of a case31, provided with a hinged cover or door 32, closed by a latch 33 andcontaining compartments 34 for the convenient and safe storage of theoperators tools and serving as a base for the head rest or roll 35,which is carried by a stem 36, provided with. ratchet-teeth or notches.This rests within a sleeve 37, Fig. 4, under the control of aspring-actuated pin 38, arranged to engage the notched stem with one endand serving as a push-button to grasp and release the stem 36, by whicha longitudinal adjustment of the roll 35 is secured. The sleeve 37 has atransverse and preferably curved slot 39 near the inner end, withinwhich slot passes a pin 40, which is arranged and serves as a fulcrumforthe pivotal movementof the sleeve. The inner end of the sleeve isrounded and provided with teeth 41, which are engaged by one arm of thepawl 42 under the iniiuence of the spring 43. A pin 44 serves to actuatethe pawl 42 against the tension of the spring, and thus release thesleeve 37. As the roll-bearing stem may be drawn in and out of thesleeve and the sleeve can be moved through an arc of approximately onehundred degrees about the pin 40, it will be see-n that an exceedinglywide range of adjustment is thus secured for the head -supporting rolleven when the case 31 remains fixed in one position.

The case 31 is supported upon the rods 45, the ends of which arepivotally mounted in standards 46, carried by the base-plate. Side bars47, lying alongside the seat and having their front ends connected withthe foot-rest portion, as will be hereinafter more fully described, arejoined intermediate their length by the curved links 48 with the upperrear side of the ease 31 in such manner that the raising and lowering ofthe rear end of the side bars will tip the case forward, thus increasingthe range of adjustment of the headsupporting roll 35. Thislast-described movementis effected through the medium of hooked arms 49,bearing, respectively, upon the upper and lower sides of the rear endsof the two side bars and fixed upon the rock-shaft 50, controlled by thelever 51. An arm 52, fast to the rock-shaft and connected by a spring 53with a fixed portion of the chair, serves to equalize the forces exertedupon the shaft.

The foot-rest portion is supported from the main frame of the chair bythe swinging rods 54, which are connected near their middle with theside bars 47, either directly or by means of the links 55. Across thelower side of the platform extend guide-rods 57, upon which slides abase 58, carrying a frame 59, playing through the slot 59'. A lever 60,fulcrumed at 61 and having an upturned handle 62, is connected by a link63 with the sliding base 58. By this means the entire base and frame 59can be withdrawn to one side to leave the central portion of theplatform clear as the customer enters and leaves the chair.

The frame 59 is itself provided with hori- Zontally-disposed rods whichserve as guiderods extending' forward and backward. These rods supportthe laterally-extending undercut shoulders of the foot-rest support ofslide 64, which forms a sleeve for the reception of the stem 65 of thefoot-roll 66. The stem 65 is formed with a number of conicalratchetteeth 67, which receive the spring-pressed dog 68, whereby thestern is held against downward movement, but may be freely rotated. Afoot-rest bar 69 is connected by the side pieces 7 0 with the axle ofthe roll and is adjusted into proper position by a hook 71, thcdeflected shank of which abuts against the side of the roll-stem andwhose jaws receive the loose end of a bar 72, which is hinged to asliding clevis 73, carried by the foot-bar 69.

The chair is thrown from the normal position, as shown in Fig. 1, intothe reclining or shaving position, as shown in Fig. 2, by virtue of theconnections already described and by means of the mechanism as follows:

A rock-shaft 74 is provided with two arms 75, connected by curved links76 with the swinging rods 54, which support the hori- Zontal platform56. This rock-shaft 74 is actuated by a lever 77 and is provided withthe usual supplemental lever-rod 78, which carries a dog to engage aseries of recesses or teeth 79 in the segment 80, whereby the lever andshaft are held in adjusted position. It will be seen that as the lever77 is thrown from theposition shown in Fig. 1 to that` shown in Fig. 2the links 76 will push the rods 54 forward into an inclined' positionwith the platform and foot-rest swinging upon the pivot at 8l. In sodoing the side bars 47, connected thereto by the links 55, are drawnforward and, by means of thecurved links 48, tilt the case 3l and thehead-supporting roll backward to bring the parts of the chair into aproper reclining position. Areversal of the movement will again restorethe'normal upright position.
